KNSCHA
Strong match with identical key electrical parameters and package. A likely pin-to-pin replacement.
Find and compare substitutes for the Fujicon CK1H010M-CRC54, a 1uF 50V SMD aluminum electrolytic capacitor. This page analyzes potential alternatives based on key electrical and physical parameters.
Key electricals match. Secondary parameters like ESR should be checked.
Package dimensions match, but land pattern should be confirmed from datasheet.
Availability and lead time of alternatives should be verified with distributors.
Direct replacement for CK1H010M-CRC54 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The KNSCHA RST1UF50V017 is the most promising direct replacement path, matching all key parameters.
The primary risk is ensuring the physical land pattern and pinout are identical, as this is inferred from package data, not a direct pinout diagram comparison.
